11 Claims. (Cl. 12B- 38) Fig.- 1 is an inside plan view of the openbinder;

Fig. 2 is a section online 2 2 of Fig. l;

Fig. 3 is Yan end View looking up in Fig. l; and Figs.'4, 5, and 6 aredetail views of parts. A suitable binding case'is represented by thereenforced curved back panel 2 and hinged covers I. The particularembodiment of the invention as disclosed has a metal plate `3 with edgeflanges 4 fastenedon the inside curved face of the back panel 2. Thisplate 3 has a set of spaced posts 5 rigidly mounted with screw threadedrecesses to receive screws 6. On plate 3 I mount an angular plate 1.This plate as shown consists of two equal flat sides meeting at an anglein the center of the book. The screws 6 hold the plate 1 in place withheads in countersunk relation to the top of the plate and Shanksthreaded in posts 5. v At the outer edges of 'plate 1 I preferably bendflanges 8 downwardly about as shown to make good contact with the backpanel just inside the hinge lines. These flanges 8 with flanges 4 givevery good supportto theangle plate 1 at the sides.

' vThe space between plate 1 and plate 3 is closed at the upper andlower ends of the book. I prefer to make the closure at one end by apermanent closure plate 9, and at the other end by a hinged plate I0 tobe readily opened and closed as a door, and with a spring latch II tonormally'hold plate I0 in closed position.

The hinged closure is seen in Figs. 3, 5, and 6. It consists of a singlestamping with studs I2 which may pivot in corresponding holes in anges4. A spring tongue II may be struck up out of plate 3 to serve as latchII in the manner clearly indicated in Figs. 3 and 5. It will be seenthat platel will act as a closure in the position of Fig. 3 for that endof the space between plates 3 and 1 of Fig. 2, and this closure may beopened on hinges I2 by turning it, the spring latch II acting in theposition of Fig. 5 to keep the door closed. I prefer to have the door atthe top of the book, but of course it may be at either end.

I provide a partitioned hood at each end of plate 1. The hood I3 may bemade as part of end closure plate 9 fastened permanently to the plateable ways.

vtion walls. The advantage of having such subprovide for such freeaction at th-e back of the book. This is one reason I make the angle 'lin anysuitable way. This is shown `in Fig. 4. The partitions I4 of thehoods may be made by striking up metal from plate 1 or in other` suit-The hood I5 may be made bya strip g of metal permanently fastened inany'suitable 5 Way to plate 1 in the position of Figi. 2. The plate ordoor III forms the outer closure for'the partitioned spaces, as plate 9does for hood I3.

The parts shown in Fig. 4 comprising principally plate 1 are fastened tothe plate 3 by screws 10 6 after plate 3 of Fig. 5 is fastened to theback panel. Or posts 5 may be mounted permanently on the back panel andthe` whole assembly of Fig. 6 fastened by screws 6 to posts 5. When thestructure is made up into bookV form the general operation is asfollows: The pamphlets are placed one by one with their back foldsagainst plate 1. With end door It) open, a straight wire I6 is passedbetween the leaves or" each pamphlet. The ends of wires I6 are thenlocated inside the 20 hoods I3 and I5 and when the door IIJ is closedandrlatched the pamphlets are bound. A reserve supply of wires I6 isconveniently held in the space between plates 1 and 3 to which access ishad when the door Ill is open. 25

In my improved construction I provide for holding only a few pamphletsor many pamphlets, as occasion may arise in the use of `the binder.

In holding a few, say four thin pamphlets,`one may be held by each wireIB and each wire placed 30 between partition walls I4, as in Fig. 2.This will hold them in loose, spread-out arrangement, very easy forindividual examination, as they cannot crowd together when the binder isopen. Each wire I6 holds its pamphlet securely in the binder, 3D yetwith a substantial freedom of movement. Partition walls I4 limit themovement of each Wire so its ends cannot work out from under end hoodsI3 and I5, as they could but for the partistantial freedom is that thewires are not liable to cramp. Each one may shift freely between thepartition walls, but not enough to work out. The proportion andconstruction should be such as to plate 1 flat sided. It gives rod I 6 afreedom of movement. With only a few pamphlets in the binder, eachv oneis very easily examined and the 50 others moved out of the way, withoutgetting any of their holding wires jammed.

When the binder is fairly well filled with pamphlets, there is thisadvantage: Partition walls I4 keep the pamphlets fairlyV well separated55 and balanced so that they cannot all crowd over to one side. One-halfmay be bound above one at side of plate l, and the other half on theflat other side. The angle between these two sides increases thecapacity of the book by making the two fiat sides longer than if asingle at side were used the width of the back panel. The angle is suchthat the pamphlets when opened will lie out substantially at. When mybinder is opened, there is a distinct tendency for the filling materialto fall down on each cover in well balanced condition. The back bindingis loose enough to provide for this. Each half at the back is free toslide down the inclined fiat side against the adjacent cover. And yetthose from one side may be picked up and laid over on the other side.With their loosely held back wires, the manipulation of the filler andits parts is very convenient.

Having disclosed and described my improved binder, I claim:

1. In a binder of the kind described having a back panel and hingedcovers, the combination of an angle plate attached above the back paneland having two at sides with the angle above the center line of the backpanel, a narrow hoodl portion at each end of said angle plate, saidhoods having cross partitions, retaining Wires adapted to extend fromhood to hood and be held adjacent said iiat sides for free lateralmovement thereon but limited by said cross partitions from sliding toofar askew on the angle plate to work loose from the binder.

2. In a binder of the kind described having covers hinged to a backpanel, the combination of a flat sided angle plate having its areacovering the inside of the back panel and spaced above the latter, theupper surface of said plate being flat sided and pitched dow .wardlyfrom the center toward the sides, means located at opposite ends of saidangle plate to retain wires running from one end to the other, saidretaining means being loose enough to permit the wires to slide freelyon said plate. Y

3. A binder comprising covers hinged to a back panel, an angle plate oftwo flat sides angularly arranged to span the space between the hingelines with a slight downward pitch from the center line toward eachcover, retaining Wires for pamphlets adapted to slide freely down saidat sides, and means at the opposite ends of the binder to hold saidwires loosely in relation to said plate.

4. The binder of claim 3 in combination with means to limit the movementof the retaining wires on the downwardly pitched at sided plate.

5. The binder of claim 3 in combination with means to prevent saidretaining wires from passing the center line of said plate. y

6. A binder comprising a back panel and covers hinged thereto, meansmounted at the opposite ends of the back panel to loosely retain theends of wires whereby pamphlets may be bound, an angle plate mounted onthe inside and above the back panel to hold the wires and boundpamphlets for easy and free movement at the back,

said angle plate having flat sides oppositely pitched from the centerline and means to stop the wires from traveling across said plate fromone pitched side to the other or more than a part of the way on eachside.

7. A binder of the kind described including a back panel, hinged coversconnected thereto, and means to hold pamphlets loosely between thecovers, said means consisting in a wire to be placed in the fold of eachpamphlet, a support spanning the back panel for the pamphlet backs torest and slide against, said support having two oppositely pitched flatsides arranged to facilitate pamphletssliding down some against onecover and some' against the other cover when the book is opened,` cagesone at each end of the back panel to retain the'ends of the retainingwires from. falling out, said cages having retaining means to allow veryfree shifting of the wire ends betweenv predetermined limits Withoutbinding. v S. The combination of a curved back panel plate having sideflanges, a spaced covering plate made with two flat equal sides like apitched roof and having side flanges toed over the flanges of the backpanel plate, means to fasten said plates together, a, cage extendingacross each end of the covering plate with partitions between whichbinding wires are adapted to lie for free but limited movement acrossthe plate, end closing plates, one of which is hinged, to cover thespace between saidplates and the outside openings of said cages.

9. In a binder of the kind described having a, back panel and asupporting plate attached on the inside of the back panel of the binder,said plate having side edges braced against the edges of the back paneland two at sides pitched at a slight rise to meet in the central planeof the book, wires for loosely holding pamphlets with their backsresting on said flat sides and means at the ends of said plate to retainsaid wires in the book, said means comprising large pockets relative tothe diameter of the wires to allow for substantial but limited movementfor the ends of the wires in every direction except endwise of thewires.

10. In metallic loose leaf mechanism for book binders the combination,of a stiff panel plate to lie on the inside face of a back panel, anangle plate fastened in rigidly supported position above the panelplateand in spaced relation thereto, a hood at each end of the angleplate to hold wires from working loose when their ends are mounted undersaid hoods, end closure plates for the hoods, said angle plate beingformed with oppositely pitched flat sides meeting in the central planeof the structure, all constructed and arranged to permit free limitedmovement of pamphlets bound by wires on said structure and withoutcramping the Wires.

11. The structure of claim 10 in combination with partitions in saidhoods to prevent movement from. oneflat side of the angle plate to theother, of wires binding pamphlets in said structure.
